Maternal sleep apnea may elevate birth defects in infants

New Delhi: Babies born to mothers with chronically disrupted sleep are more likely to have higher risk of birth defects and resuscitation at birth.

Obstructive sleep apnea is a potentially serious sleep disorder which occurs when a person's throat muscles intermittently relax and block the airways during sleep and causes breathing to repeatedly stop and start during sleep.

The findings showed that newborns of mothers with sleep apnea were 25 per cent more likely to be admitted to the intensive care unit or special care nursery by 34.9 per cent.

These newborns were 2.76 times more likely to have resuscitation at birth and 2.25 times more likely to have a longer hospital stay.

The risk for congenital anomalies also was 26 per cent higher in babies of women with sleep apnea.

"Our results have shown that babies born to mothers with a diagnosis of obstructive sleep apnea are more likely to require resuscitative efforts at birth, be born preterm, and to require a stay in the neonatal intensive care unit compared to babies who were not exposed to maternal sleep apnea," said lead author Ghada Bourjeily, associate professor at the Brown University in Rhode Island, US.
